【摘要】：利用胶凝砂砾石(CSG)浇筑坝体是近年来兴起的一项新型筑坝技术。以老挝南欧江五级水电站纵向围堰施工为例,介绍利用电站坝址上下游河道的天然河滩料作为CSG骨料,并添加少量的胶凝材料,通过类似于RCC施工方法进行纵向围堰施工。工程完工后的取样分析结果及度汛情况表明,采用CSG筑坝在工程安全上是可行的,同时由于大幅缩短了工期,创造了较为可观的经济价值,相关经验可供类似工程借鉴。
[Abstract]:The construction of dam body by cementitious sand and gravel (CSG) is a new type of dam construction technology in recent years. Taking the longitudinal cofferdam construction of the fifth grade hydropower station in southern Europe as an example, this paper introduces the application of natural riverbank material in upstream and downstream channel of the dam site as CSG aggregate, and the addition of a small amount of cementing material to carry out longitudinal cofferdam construction similar to RCC construction method. The results of sampling analysis after completion of the project and the flood situation show that it is feasible to use CSG for dam construction in engineering safety, and at the same time, because the construction period has been greatly shortened, considerable economic value has been created, and relevant experience can be used for reference in similar projects.
